6/20/2023 0 Comments Op amp offset and null circuitdifferential input voltage) is essentially zero for finite output voltage.ĥ. Ideal op-amp has infinite voltage gain becauseĮxplanation: As the voltage gain is infinite, the voltage between the inverting and non-inverting terminal (i.e. Therefore, any frequency signal from 0 to ∞ Hz can be amplified without attenuation.Ĥ. An ideal op-amp requires infinite bandwidth becauseĪ) Signals can be amplified without attenuationī) Output common-mode noise voltage is zeroĬ) Output voltage occurs simultaneously with input voltage changesĭ) Output can drive infinite number of deviceĮxplanation: An ideal op-amp has infinite bandwidth. Which of the following electrical characteristics is not exhibited by an ideal op-amp?Įxplanation: An ideal op-amp exhibits zero output resistance so that output can drive an infinite number of other devices.ģ. Therefore, the output Vo is 180o out of phase with input signal V2.Ģ. Determine the output from the following circuitĮxplanation: The input signal is given to the inverting input terminal.
